I agree that this is not cleanly working and I hope Intuit can address this in the application. They have an online help article that was just edited this week on the entry of the sale of a second home and its instructions do not match the screen in the application. Even if you proceed to use the current screen, the long term/short term pulldown menu still refers to boxes from a 1099-B form. And if you fill out the data fields provided, the underlying worksheet forms populate with unclear data. There is no reference to the sale of a second home at all. This should be addressed better in the application. The way it is now, I don't have any confidence that it is being handled correctly. Too many loose ends.
